Title: Identification of a human cytomegalovirus gene region involved in down-regulation of mhc class i heavy chain expression
Inventor: CAMPBELL ANN E
IPC: C12N15/86
Filed: 1995-07-28
Granted: 2004-09-21
Abstract: Infection of human fibroblast cells with human cytomegalovirus (HCMV) causes down-regulation of cell surface expression of MHC class I. The present invention is directed to a mutant with a 9-kb deletion in the S component of the HCMV genome (including open reading frames IRS1-US9 and US11) which fails to down-regulate class I heavy chains. By examining the phenotypes of mutants with smaller deletions with this portion of the HCMV genome, a 7-kb region containing at least 9 open reading frames was shown to contain the genes required for reduction in heavy chain expression. Furthermore, it was determined that two subregions (A and B) of the 7-kb region each contained genes which were sufficient to cause heavy chain down- regulation. In subregion B, the US11 gene product is involved. It encodes an endoglycosidase H-sensitive glycoprotein which is intracytoplasmic, similar to the adenovirus type 2 B3-19K glycoprotein which inhibits surface expression of class I heavy chains.

Title: System and method for controlling and monitoring communication between customers and customer service representatives
Inventor: SCHRYER NORMAN LOREN
IPC: H04M3/51
Filed: 1997-04-02
Granted: 2000-08-01
Abstract: The system of the present invention allows a customer to access a company computer system via a data network and to request contact with a customer service  representative.     The  company  computer system  automatically  selects  a  customer  service center  and  a  customer  service  representative  in accordance  with  a  set  of  selection  criteria, including customer preferences.   A monitor,  also connected to the company computer system via the data network, may choose to accept or to change the selections made by the company computer system. Once  a  customer  service  representative  has  been selected,  the  company  computer  system  causes  a telecommunication  control  device  to  connect  the customer,    the    selected    customer    service representative,   and  the  monitor  via  a  voice network.    If  a  monitor  is  not  available,  the company     computer     system     causes     the telecommunication  control  device  to  connect  the customer   and   the   selected   customer   service representative, and then records the communication therebetween  for  future  review  by  a  monitor. Optionally,    the    selected   customer   service representative may initiate data communication with the customer via the data network.  The monitor may readily monitor the data communication between the customer and the  customer  service  representative via the data network.

Abstract: Vinyl sulfides bearing protected arlyoxy substituents and a process for their preparation are provided. In the process a vinyl sulfide is formed by coupling a ketone compound and a thioester compound with a low valent titanium reagent to form both carbon-carbon bonds in the same step. The vinyl sulfide compounds are useful as intermediates which are convertible into triggerable sulfur-substituted dioxetanes by addition of oxygen to the double bond. The sulfur-substituted dioxetanes additionally are useful for producing chemiluminescence or for further conversion into triggerable alkoxy, alkenyloxy, alkynyloxy, aryloxy, aralkyloxy or acyloxy-substituted dioxetanes. Triggerable dioxetanes are useful for producing chemiluminescence and in detecting activating agents in assays such as immunoassays and nucleic acid hybridization assays.

Title: Removal of carbonyl impurities from a carbonylation process stream
Inventor: SCATES MARK O
IPC: C07C51/487
Filed: 1996-09-06
Granted: 2007-01-09
Abstract: A process to reduce carbonyl impurities in a carbonylation reaction for the production of acetic acid is described. The methyl iodide recycle stream which is directed to a carbonylation reactor for carbonylating methanol or methyl acetate to acetic acid, is treated to remove carbonyl impurities by reacting the methyl iodide stream formed in the reaction with an aqueous amino compound which reacts with the carbonyls to form water soluble nitrogenous derivatives, separating an organic methyl iodide phase from an aqueous derivative phase and distilling the methyl iodide phase to remove heavier impurities. The treatment of the methyl iodide recycle stream to the carbonylation reactor has been found to greatly reduce the carbonyls present in the acetic acid product. The formation of nitrile from the nitrogenous derivative during distillation may be minimized by adding water to the system.

Title: Optical fiber probe for position measurement

IPC: A61B19/00
Filed: 1998-06-04
Granted: 2006-05-30
Abstract: Improved point source electromagnetic radiation emitters including a dispersing element that radiates electromagnetic radiation over a very wide conical angle of approaching about 180°. This light dispersing element can be in any one or more of several illustrated forms such as a light diffusing spherical or hemispherical element, a planar diffusing plate, a tapered light guide, a piano-concave lens, a convex mirror, a light pipe with a large numerical aperture, or the like. The emitter of this invention may be fixed to an object and tracked in a 3-dimensional volume by a system using electro-optical position sensors in order to determine the spatial location of the emitters and therefore to determine, by geometry, the position and orientation of the object. The electromagnetic radiation generator is preferably disposed remote from the emitter and is electrically and magnetically isolated from the emitter. A common optical fiber provides transmission of the radiation from the generator to the emitter. The emitted radiation more nearly resembles point source of radiation and therefore enables more accurate determination of the location of the radiating element, and thereby more accurate determination of the position and orientation of the object on which the emitters reside. The preferred electromagnetic radiation generator is an LED, most preferably a laser diode.

Abstract: A rotary electric apparatus; and a generator and a motor respectively using the rotary electric apparatus. Said rotary electric apparatus comprises a rotary shaft (1), a stator (2) being disposed by way of surrounding external periphery of the shaft (1), and a pair of rotors (3N) and (3S) integrally disposed onto the shaft at both-side positions of the stator (2). The rotor (3N) comprises a plurality of N-polar magnetic poles and the other rotor (3S) comprises S-polar magnetic poles by the same number as that of the rotor (3N). The N and S magnetic poles set to the rotors are disposed at equal angles in the state of being opposed to each other in the axial direction of the shaft (1). The stator (2) comprises cores that correspond to double number of magnetic poles of each rotor, magnetic-pole portions formed at both ends of said cores, and coils wound on said cores. The magnetic-pole portions both ends are respectively disposed at equal angles in the state of being opposed to the magnetic poles of the rotors via air-gap. By virtue of the above structure, magnetic poles provided for the rotors (3N)(3S) can be formed with flat surfaces, thus securing even magnetic flux. Further, as a result of contraction of the stator (2) in the axial direction, iron loss and leakage flux can securely be minimized.
